I have 2 tanks and one with a .16 and my normal one with .4 ohm. I generally vape 3mg and on my .4 and it is perfect for me and in my .16 ohm coil, it is a bit stronger, but not too much. Now I also came across a bunch of 6mg juice and in my .4 it is stronger, but it is very strong on my .16 ohm coil. I am only using that super low ohm coil because it came as a spare in my Baby Beast tanks. But once those burn out.. I should only be on the .4 ohm coils.
